Cold Storage Between Jupiter and Mars | Cosmos: A Spacetime Odyssey

are there any mementos from when the
earth was born object that could
possibly tell us its true age I know a
place where the unused bricks and mortar
left over from the creation of our solar
system can be found it lies between the
orbits of Jupiter and Mars here is the
stuff of the newborn earth adrift in
cold storage unchanged ever since that
time a million or so years ago a large
asteroid happened to jostle a much
smaller one sending it on a new
trajectory a collision course that ended
one night some 50,000 years ago
